BACKGROUND

Cardiovascular disease is one of the leading causes of death in the United States and most European countries. It is estimated that over 70 million people in the United States alone suffer from a cardiovascular disease or disorder including but not limited to high blood pressure, coronary heart disease, dislipidemia, congestive heart failure and stroke. A need exists for improved treatments for cardiovascular diseases and disorders.

It is further estimated that more than 6 million Americans suffer from some form of seafood allergy. Sicherer et al., Journal of Allergy and Clinical Immunology, Volume 114, Issue 1, Pages 159-165. Therapies derived from fish oil have been proven effective at lowering triglycerides, among other effects. Unfortunately, such products are contraindicated in subjects that are allergic or hypersensitive to fish.

The term “cardiovascular-related disease” herein refers to any disease or disorder of the heart or blood vessels (i.e. arteries and veins) or any symptom thereof. Non-limiting examples of cardiovascular-related disease and disorders include hypertriglyceridemia, hypercholesterolemia, mixed dyslipidemia, coronary heart disease, vascular disease, stroke, atherosclerosis, arrhythmia, hypertension, myocardial infarction, and other cardiovascular events.

The term “treatment” in relation a given disease or disorder, includes, but is not limited to, inhibiting the disease or disorder, for example, arresting the development of the disease or disorder; relieving the disease or disorder, for example, causing regression of the disease or disorder; or relieving a condition caused by or resulting from the disease or disorder, for example, relieving, preventing or treating symptoms of the disease or disorder. The term “prevention” in relation to a given disease or disorder means: preventing the onset of disease development if none had occurred, preventing the disease or disorder from occurring in a subject that may be predisposed to the disorder or disease but has not yet been diagnosed as having the disorder or disease, and/or preventing further disease/disorder development if already present.

In one embodiment, the present invention provides a method of blood lipid therapy comprising administering to a subject or subject group in need thereof a pharmaceutical composition as described herein. In another embodiment, the subject or subject group has hypertriglyceridemia, hypercholesterolemia, mixed dyslipidemia and/or very high triglycerides.

In another embodiment, the subject or subject group being treated has a baseline triglyceride level (or mean or median baseline triglyceride level in the case of a subject group), fed or fasting, of about 200 mg/dl to about 500 mg/dl. In another embodiment, the subject or subject group has a baseline LDL-C level (or mean or median baseline LDL-C level), despite statin therapy, of about 40 mg/dl to about 100 mg/dl.

In one embodiment, the subject or subject group being treated in accordance with methods of the invention is on concomitant statin therapy, for example atorvastatin, rosuvastatin or simvastatin therapy (with or without ezetimibe). In another embodiment, the subject is on concomitant stable statin therapy at time of initiation of ultra-pure EPA therapy.

In another embodiment, the subject or subject group being treated in accordance with methods of the invention has a body mass index (BMI or mean BMI) of not more than about 45 kg/m².

In one embodiment, the invention provides a method of lowering triglycerides in a subject on stable statin therapy having baseline fasting triglycerides of about 200 mg/dl to about 500 mg/dl, the method comprising administering to the subject a pharmaceutical composition comprising about 1 g to about 4 g of EPA (e.g. ultra-pure EPA), wherein upon administering the composition to the subject daily for a period of about 12 weeks the subject exhibits at least 10%, at least 15%, at least 20%, at least 25%, at least 30%, at least 35%, at least 40%, at least 45%, at least 50%, at least 55%, at least 60%, at least 65%, at least 70%, or at least 75% lower fasting triglycerides than a control subject maintained on stable statin therapy without concomitant ultra-pure EPA for a period of about 12 weeks, wherein the control subject also has baseline fasting triglycerides of about 200 mg/dl to about 500 mg/dl. The term “stable statin therapy” herein means that the subject, subject group, control subject or control subject group in question has been taking a stable daily dose of a statin (e.g. atorvastatin, rosuvastatin or simvastatin) for at least 4 weeks prior to the baseline fasting triglyceride measurement (the “qualifying period”). For example, a subject or control subject on stable statin therapy would receive a constant daily (i.e. the same dose each day) statin dose for at least 4 weeks immediately prior to baseline fasting triglyceride measurement. In one embodiment, the subject's and control subject's LDL-C is maintained between about 40 mg/dl and about 100 mg/dl during the qualifying period. The subject and control subject are then continued on their stable statin dose for the 12 week period post baseline.

In one embodiment, the statin is administered to the subject and the control subject in an amount of about 1 mg to about 500 mg, about 5 mg to about 200 mg, or about 10 mg to about 100 mg, for example about 1 mg, about 2 mg, about 3 mg, about 4 mg, about 5 mg, about 6 mg, about 7 mg, about 8 mg, about 9 mg, or about 10 mg; about 15 mg, about 20 mg, about 25 mg, about 30 mg, about 35 mg, about 40 mg, about 45 mg, about 50 mg, about 55 mg, about 60 mg, about 65 mg, about 70 mg, about 75 mg, about 80 mg, about 90 mg, about 100 mg, about 125 mg, about 150 mg, about 175 mg, about 200 mg, about 225 mg, about 250 mg, about 275 mg, about 300 mg, about 325 mg, about 350 mg, about 375 mg, about 400 mg, about 425 mg, about 450 mg, about 475 mg, or about 500 mg.

In another embodiment, any of the methods disclosed herein are used in treatment of a subject or subjects that consume a traditional Western diet. In one embodiment, the methods of the invention include a step of identifying a subject as a Western diet consumer or prudent diet consumer and then treating the subject if the subject is deemed a Western diet consumer. The term “Western diet” herein refers generally to a typical diet consisting of, by percentage of total calories, about 45% to about 50% carbohydrate, about 35% to about 40% fat, and about 10% to about 15% protein. A Western diet may alternately or additionally be characterized by relatively high intakes of red and processed meats, sweets, refined grains, and desserts, for example more than 50%, more than 60% or more or 70% of total calories come from these sources.

In another embodiment, any of the methods disclosed herein are used in treatment of a subject or subjects that consume less than (actual or average) about 150 g, less than about 125 g, less than about 100 g, less than about 75 g, less than about 50 g, less than about 45 g, less than about 40 g, less than about 35 g, less than about 30 g, less than about 25 g, less than about 20 g or less than about 15 g of fish per day.

In another embodiment, any of the methods disclosed herein are used in treatment of a subject or subjects that consume less than (actual or average) about 10 g, less than about 9 g, less than about 8 g, less than about 7 g, less than about 6 g, less than about 5 g, less than about 4 g, less than about 3 g, less than about 2 g per day of omega-3 fatty acids from dietary sources.

In another embodiment, any of the methods disclosed herein are used in treatment of a subject or subjects that consume less than (actual or average) about 2.5 g, less than about 2 g, less than about 1.5 g, less than about 1 g, less than about 0.5 g, less than about 0.25 g, or less than about 0.2 g per day of EPA and DHA (combined) from dietary sources.

Seafood/fish allergies often manifest as hives, itching, and eczema (rash). These reactions among those with fish allergies prevent patients from benefiting from the cardiovascular, anti-inflammatory, neurological, endocrine and other benefits of pharmaceutical grade fish oil derivatives by decreasing compliance. In various embodiments, the invention provides compositions and methods as described herein wherein the subject does not exhibit skin rash, or exhibits reduced skin rash incidence compared to placebo.

Another shortcoming of fish oil derived therapies and medicines are the incidence of eructation, or “fishy burp”. In various embodiments, the invention provides compositions and methods as described herein wherein the subject does not experience eructation or experiences reduced eructation compared to Lovaza therapy.

In one embodiment, a composition as described herein is administered to a subject once or twice per day. In another embodiment, 1, 2, 3 or 4 capsules, each containing about 500 mg to about 1 g of a composition as described herein, are administered to a subject daily. In another embodiment, 1 or 2 capsules, each containing about 1 g of a composition as described herein, are administered to the subject in the morning, for example between about 5 am and about 11 am, and 1 or 2 capsules, each containing about 1 g of a composition as described herein, are administered to the subject in the evening, for example between about 5 pm and about 11 pm.

In one embodiment, a subject being treated in accordance with methods of the invention is not on fibrate or nitrate therapy.

In another embodiment, compositions useful in accordance with methods of the invention are orally deliverable. The terms “orally deliverable” or “oral administration” herein include any form of delivery of a therapeutic agent or a composition thereof to a subject wherein the agent or composition is placed in the mouth of the subject, whether or not the agent or composition is swallowed. Thus “oral administration” includes buccal and sublingual as well as esophageal administration. In one embodiment, the composition is present in a capsule, for example a soft gelatin capsule.

A composition for use in accordance with the treatments of invention can be formulated as one or more dosage units. The terms “dose unit” and “dosage unit” herein refer to a portion of a pharmaceutical composition that contains an amount of a therapeutic agent suitable for a single administration to provide a therapeutic effect. Such dosage units may be administered one to a plurality (i.e. 1 to about 10, 1 to 8, 1 to 6, 1 to 4 or 1 to 2) of times per day, or as many times as needed to elicit a therapeutic response.

In another embodiment, the invention provides use of any composition described herein for treating moderate to severe hypertriglyceridemia in a subject in need thereof, comprising: providing a subject having a fasting baseline triglyceride level of about 500 mg/dl to about 1500 mg/dl and administering to the subject a pharmaceutical composition as described herein.

EXAMPLES

The following examples are for illustrative purposes only and are not to be construed as limiting in any manner.

Example 1

A single center, double blind, randomized, parallel-group, placebo controlled dose-ranging study of E-EPA in subjects with age-associated impairment (AAMI) was performed. The primary goal was to examine the effect of ethyl-EPA versus placebo on cognitive performance in subjects with AAMI as measure by the power of attention tasks in a computerized test batter over a period of 6 weeks. Secondary objectives were to:

(1) examine the effect of E-EPA versus placebo over 6 weeks on the following tests in the computerized cognitive battery: Continuity of attention tasks; Quality of working memory tasks; Quality of episodic memory tasks; Speed of attention tasks;

(2) to assess the safety and tolerability of E-EPA versus placebo from routine clinical laboratory tests, adverse events (AE) monitoring and vital signs; and

(3) assess the potential dose-effect relationship of E-EPA on the cognitive endpoints by measurement of essential fatty acids in plasma and red blood cell membranes. 94 subjects were randomized.

The study plan was to enroll 96 subjects who would be randomly allocated to 1 of 4 possible treatment groups for 6 weeks, in a balanced block design (24 subjects per group), as follows:

1. 1 g ethyl-EPA daily

2. 2 g ethyl-EPA daily

3. 4 g ethyl-EPA daily

4. Placebo (paraffin oil) daily

Ethyl-EPA was provided as 500 mg soft gel capsules providing ethyl-EPA of >96% purity, 0.25% to 0.38% by weight ethyl octadecatetraenoate, 0.075% to 0.15% by weight ethyl nonaecapentaenoate, 0.25% to 0.35% by weight ethyl arachidonate, 0.3% to 0.4% by weight ethyl eicosatetraenoate (ETA-E), 0.075% to 0.15% ethyl heneicosapentaenoate and 0.2% dl-□-tocopherol as an antioxidant. Matching placebo capsules contained 467 g of liquid paraffin and 0.2% dl-□-tocopherol. The placebo group was further randomized so that an equal number of subjects (8) was allocated 1 g, 2 g or 4 g placebo. Study drug was taken twice daily (BID) as a divided dose (e.g. for the 1 g dose, 500 mg was given in the morning and a further 500 mg was given in the evening) with a light snack or meal.

The study consisted of a screening visit, a training visit and 4 study visits. At the screening visit, subjects' eligibility was determined through cognitive tests (verbal paired associated learning [PAL] subscale, vocabulary subtest, Memory Assessment Clinics Questionnaire [MAC-Q], mini mental state evaluation [MMSE] and MINI [mini international neuropsychiatric interview; sections 1 and 2 of Diagnostic and Statistical Manual of Mental Disorders, 4th Ed. (DSM-IV) plus dysthymia]), haematology, clinical chemistry and 12-lead electrocardiogram (ECG). At the training visit, subjects were shown how to use the CDR computerized system. Subjects took study drug for 6 weeks and on Days 0, 14, 28 and 42, subjects underwent the CDR cognitive test battery.

Every reasonable effort was made to document subject outcome and reasons for withdrawal. Any ongoing AEs were followed-up until the event had resolved, stabilized or was otherwise explained. Subjects who were withdrawn were not replaced. Subjects were assigned unique identification numbers according to a pre-determined randomization list generated by Catalent Pharma Solutions and used in the drug packaging.

Study drug was administered orally BID as a divided dose with food, for 6 weeks. Subjects were randomized to 1 of 6 possible treatment groups (Table 1).

TABLE 1 Treatment Groups Dosage Form (soft gel capsule) Group Dose (g) Study Drug Dosage Form (soft Group Dose (g) Study Drug gel capsule) Active 1 1 Ethyl-EPA 1 x 500 mg BID Active 2 2 Ethyl-EPA 2 x 500 mg BID Active 3 4 Ethyl-EPA 4 x 500 mg BID Placebo 1 1 Paraffin oil 1 x 500 mg BID Placebo 2 2 Paraffin oil 2 x 500 mg BID Placebo 3 4 Paraffin oil 4 x 500 mg BID BID = twice daily, ethyl-EPA = ethyl-eicosapentaenoic acid

Study drug was dispensed at Visits 3, 4 and 5; the maximum period between Visit 3 and each subsequent visit was:

All treatment packs were identical in appearance, in order to maintain subject and investigator blind throughout the study. The investigator, Sponsor/clinical research organization personnel and subjects remained blinded throughout this study. The investigator was permitted to un-blind individual subjects if it was considered medically imperative. The process for breaking the blind is outlined below.

Omega-3 supplements had to be discontinued at least 4 weeks prior to the baseline visit (Visit 3). Cough and influenza remedies containing opiates or antihistamines had to be discontinued 2 weeks prior to the baseline visit (Visit 3) and were not permitted for the duration of the study.

Existing medication had to have been stable for 4 weeks prior to the baseline visit (Visit 3) and the dose maintained for the duration of the study. Where a dose change was absolutely necessary this was recorded in the electronic case report form (eCRF).

Subjects who required anticoagulant medication during the study were to be withdrawn. Psychological counseling or therapy was not permitted for the duration of the study, as these could have interfered with the outcome of the study. Unused study drug was returned to the study site. Subjects who used less than 80% of the prescribed dose were considered non-compliant.

At screening cognitive testing and suitability for the study were assessed using the Verbal Paired Associates 1 (Wechsler Memory Scale), Vocabulary Subtest of the WAIS, MAC-Q, MMSE and MINI (DSM-IV Sections 1 and 2 plus Dysthymia).

A selection of tasks from the CDR computerized cognitive assessment system were administered (Appendix 8 of protocol) at Visit 2 (training visit), Visit 3 (baseline), Visit 4 (Day 14), Visit 5 (Day 28) and Visit 6 (Day 42). Parallel forms of the tests were presented at each testing session. All tasks were computer-controlled, the information presented on high resolution monitors, and the responses recorded via a response model containing 2 buttons 1 marked ‘no’ the other ‘yes’. Five CDR composite scores were used as the primary/secondary outcome variables.

The task titles were:

Word Presentation Numeric Working Memory Immediate Word Recall Delayed Word Recall Picture Presentation Word Recognition Simple Reaction Time Picture Recognition Digit Vigilance Bond-Lader Visual Choice Reaction Time Analogue Scales of Mood Spatial Working Memory and Alertness Screen, Using the Computer Mouse

To ensure consistency of approach, full training on the cognitive tests and CDR test battery was provided to study site staff and study subjects. The results of each variable were automatically recorded using the machine interface developed by CDR.

An AE was defined as any untoward medical occurrence temporally associated with the use of a medicinal product whether or not considered related to the medicinal product.

The investigator was responsible for the detection and documentation of AEs. At each visit the subject was asked about AEs by means of non-leading questions. AEs were recorded from the time a subject provided a written informed consent and deemed eligible to participate until completion of the treatment period. AEs ongoing at the end of the treatment period were followed until resolution or return to baseline or normal value or if the event was considered unrelated to study drug.

A serious adverse event (SAE) was defined as any AE at any dose that:

-   -   resulted in death;     -   was life-threatening;     -   required hospitalization or prolongation of existing         hospitalization;     -   resulted in disability or incapacity, or     -   resulted in a congenital anomaly/birth defect.

Other events were considered SAEs if they jeopardized the subject or required medical or surgical intervention to prevent one of the outcomes listed above.

Regardless of the above criteria, any AE that the Sponsor or investigator considered serious was to have been immediately reported as a SAE. Any death or SAE experienced by the patient while receiving or within 30 days of last dose of Investigational Medicinal Product must be promptly reported (within 24 hours of learning of the event) to pharmacovigilance. All AEs (including SAEs) are to be accurately recorded on the adverse event page of the subject's eCRF, beginning from first administration of Investigational Medicinal Product until 30 days after the last dose.

Blood samples for the laboratory assessments for haematology (a 5 mL blood sample) and clinical chemistry (a 10 mL blood sample) listed in Table 2, were collected at the screening visit (Visit 1). Samples were processed and analyzed by Simbec Laboratories Ltd.

Pharmacodynamic: Essential Fatty Acid (EFA) Measurements

Blood samples (10 mL) were collected at Visit 1 (screening) and at Visits 4, 5 and 6. Analysis was performed by MSR Lipid Analysis, Scottish Crop Research Institute, Dundee, UK. The screening sample acted as baseline for the EFA measurements.

Lipid was extracted from plasma, serum and RBC suspensions and converted into fatty acid methyl esters which were analyzed by gas chromatography to give fatty acid profiles as micrograms fatty acid per gram of sample (μgFA/g) and normalized area percent. The CDR computerized system has been used to measure the effects of pharmaceuticals on cognitive function in a variety of clinical trials. Efficacy was assessed by a battery of cognition tests designed by CDR. Safety data were analyzed by Quanticate.

Populations analyzed included:

-   -   Intent to Treat (ITT) Population: All randomized subjects with         at least 1 visit post-baseline were included in this population,         regardless of treatment actually received.     -   Per Protocol Population (PP): All randomized subjects that         completed the study, excluding significant protocol deviators,         were defined as the Safety PP population. An Efficacy PP         population was based on the Efficacy completers. The intercept         of the Safety and Efficacy PP populations defined the Study PP         Population.     -   Safety Population: All randomized subjects that received at         least 1 dose of study medication.

Summary statistics were provided for the ITT and Study PP Populations separately for all composite scores, major and supportive variables. Summary statistics were performed for both the unadjusted and difference from baseline data (i.e. the difference from the time matched pre-dose assessments on Day 0). Summary statistics were calculated by treatment, day and time-point. The summary statistics comprised n, mean, median, SD, standard error of mean (SEM), minimum and maximum values.

Difference from baseline data for each major variable was evaluated by an Analysis of Covariance (ANCOVA) using SAS® PROC MIXED Version 8.2.

Fixed effects for treatment, day, time point, treatment by day, treatment by time point, treatment by day by time-point were fitted. Subject within treatment was fitted as a repeated effect using the repeated statement. The compound symmetry covariance structure was used. Subjects' time-matched predose assessments on Day 0 were used as a covariate in the analysis. Least squares means (LS means) were calculated for treatment by day, treatment by time-point and treatment by day by time-point interaction. This formal analysis was conducted for the ITT and Study PP Populations separately.

Safety evaluations were based on the safety population. Safety and tolerability were assessed in terms of AEs, vital signs, 12-lead ECG, clinical laboratory data, medical history, and study drug compliance. Safety and tolerability data were presented by treatment group. All safety data were listed individually by subject.

RBC and plasma EFA data were collected at baseline, Day 14, 28 and 42 and summarized by visit for each treatment group. Change from baseline and percent change from baseline were also summarized. ANCOVA comparison of ethyl-EPA dose groups and ethyl-EPA versus placebo was performed.

The sample size calculation was based on Power of Attention. Ispronicline (50 mg), a neuronal nicotinic acetylcholine receptor partial agonist, in subjects with AAMI on Day 21 of repeated dosing in an earlier study showed a benefit of 61 msec (50 mg mean=−32.54, SD=61.22; placebo mean=28.25, SD=49.64) to Power of Attention. Using a pooled SD, a sample size of 15 subjects per treatment arm was considered sufficient to detect a difference of 61 msec, with 80% power and 5% significance level (no adjustment for multiple testing). As there was no prior experience with the compound or mechanism of action with these cognitive measures, a sample size of 24 subjects per treatment arm was chosen as sufficient to allow for early withdrawals.

There were no changes to the conduct of the study. The following changes were made to the planned analyses: The equation to calculate Speed of Memory was changed to SPEEDMEM (speed of memory)=SPMRT (spatial working memory speed)+NWMRT (numeric working speed)+DRECRT (word recognition speed)+DPICRT (picture recognition speed).

-   -   Subject's time-matched pre-dose assessments on Day 0 were used         as a covariate in the analysis.     -   Day 0 was removed from Day values in the list of ANCOVA variable         values. Covariate=Baseline was changed to Covariate=Time matched         predose assessments on Day 0 in the list of ANCOVA variable         values.     -   Day by Time-point was added to the list of model effects in SAS®         code for ANCOVA model.     -   F Tests table and Treatment Effects table were added to list of         ANCOVA summary tables.     -   ANCOVA summary tables were renumbered to follow on from ANCOVA         raw outputs.     -   Figures were included for Treatment, Treatment by Day, Treatment         by Time-point, Treatment by Day by Time-point effects for ANCOVA         LS means.     -   Figures were added for ANCOVA LS means differences to placebo         (95% confidence interval [CI]).     -   A post-hoc analysis was performed which compared the individual         placebo groups (1 g, 2 g and 4 g paraffin oil) with the         corresponding ethyl-EPA dose rather than to a pooled placebo         group.

Ninety-one subjects completed the study, three subjects discontinued; 2 subjects from the ethyl-EPA 2 g treatment group (1 subject due to an SAE considered unrelated to the study drug and 1 due to a protocol violation and 1 subject from the placebo 2 g group due to an AE.

For Power of Attention, there was no statistically significant effect of treatment, nor any treatment by day, treatment by time-point or treatment by day by time-point interactions. There was no LS mean difference between active treatment and placebo at any time-point. For Choice Reaction Time there were statistically significant benefits for ethyl-EPA 1 g and 2 g on Day 28, and some trends for benefit for 1 and 4 g ethyl-EPA on Day 42, versus placebo; however, no clear treatment-related pattern was observed.

Continuity of Attention did not show a difference between placebo and ethyl-EPA, except for an overall decrease for 2 g ethyl-EPA that was only visible in the ITT population. The subtask Digit Vigilance Targets Detected showed isolated decreases for active treatment versus placebo, but there was no obvious treatment-related pattern.

Quality of Working Memory was the only composite score that showed a statistically significant treatment by day interaction in the F-ratio. However, there were only isolated statistically significant decreases for ethyl-EPA 1 g and 2 g versus placebo on Days 14 and 28, and these were most likely to be due to chance and not treatment related.

Quality of Episodic Secondary Memory showed statistically significant decreases for ethyl-EPA versus placebo at various time-points. However, it seems unlikely to be an effect of active treatment as the unadjusted data showed pre-existing differences between the treatment groups that was most notable on Day 0 in the first assessment session. In difference from Baseline data that were calculated prior to ANCOVA analysis, these differences were no longer apparent. This suggests that the ANCOVA model fitted a strong negative correlation with the baseline values. This is often the case when the variability within subjects overlaps the variability between subjects.

Speed of Memory and the subtasks Spatial and Numeric Working Memory Speeds and Word and Picture Recognition Speed showed no differences in performance, in the F-ratio statistics, between Ethyl-EPA and placebo.

For Self-rated Alertness, there was no apparent difference in ratings between ethyl-EPA and placebo. There were isolated decreases in ratings for active treatment versus placebo that were unlikely to be compound related.

Self-rated Contentment showed statistically significant decreases in ratings for ethyl-EPA 2 g on Day 28. However, these individual decreases were not statistically significant. It is unlikely that this was a treatment-related effect as it was restricted to a single day and no other dose level showed a similar pattern on any other day. For Self-rated Calmness there was no difference in ratings between active treatment and placebo.

When the results of each ethyl-EPA dose and their corresponding placebo were compared (post-hoc analysis), it appeared that ethyl-EPA 4 g improved the subjects' reaction times in the attention tasks (Power of Attention, Simple Reaction Time and Choice Reaction Time). This was seen most clearly for Choice Reaction Time, where a pattern of gradual improvement over the assessment day for 4 g was seen. It is possible that a longer period of administration would clarify the effects of ethyl-EPA on these parameters.

EPA (shown in Table 3), DPAn-3 and EPA/AA ratio (data not shown) plasma and RBC values increased substantially from baseline to Day 42 for the AMR-101 1, 2, and 4 g treatment groups. AA, DHA and DGLA values decreased substantially from baseline (data not shown).

Ethyl-EPA Placebo 1 g 2 g 4 g 1 g 2 g 4 g (N = 23) (N = 24) (N = 24) (N = 7) (N = 8) (N = 8) Plasma Base- 48.3 44.9 49.1 47.5 42.1 42.5 line (31.03) (25.01) (17.23) (26.41) (16.18) (11.86) Day 14 61.2 124.6 207.7 1.6 −1.2 21.9 (26.61) (42.25) (57.05) (24.69 (19.82) (32.91) Day 28 60.3 142.2 215.2 6.5 1.6 1.3 (36.03) (46.23) (58.68) (15.46) (13.64) (14.03) Day 42 62.0 133.4 204.6 11.9 0.4 4.4 (39.43) (43.34) (80.69) (26.34) (21.18) (23.32) RBC Base- 19.8 18.9 19.8 20.4 19.3 17.2 line (10.85) (8.91) (5.28) (5.77) (6.58) (4.94) Day 14 12.3 26.9 39.5 −0.5 0.0 2.6 (7.39) (9.15) (13.16) (6.32) (7.17) (6.73) Day 28 14.5 32.9 50.2 1.5 0.0 0.6 (10.47) (10.11) (15.82) (4.16) (7.06 (4.42) Day 42 17.6 38.3 52.5 −0.2 1.0 −0.2 (11.89) (12.46) (20.56) (5.90) (8.01) (6.97)

As can be seen in Table 3, at the 2 g per day AMR101 dose, plasma EPA levels increased 297% after 42 days and at the 4 g per day AMR101 dose, plasma EPA levels increased by 417% compared to baseline or placebo control.

Grimsgaard et al. previously published an article describing serum phospholipid levels at baseline and after 7 weeks of supplementation with 4 g per day of 90% ethyl-DHA, 4 g per day of 95% ethyl-EPA with some DHA present, or corn oil. Am. J. Clin. Nutr. 1997; 66:649-59 (1997). The complete profile of additional fatty acids and ingredients present in these compositions is unknown. After supplementation over a period of 7 weeks, subjects exhibited only a 297% increase in serum phospholipid EPA compared to the increase of 417% shown above with an inventive composition. A comparison of other chances in plasma/serum fatty acids is shown in Table 4.

TABLE 4 Percent Fatty Acid Change from Baseline After Administration of 4 g Dose Fatty Acid Grimsgaard AMR101 EPA  +297%  +417% AA −18.5% −21.9% DHA −15.20%  −17.5% DPA  +130%  +147% DGLA −30.5% −39.4%

Furthermore, in the Japanese Eicosapentaenoic Acid (EPA) Lipid Intervention Study (DELIS), Yokoyama et al. reported that they followed over 18,000 patients randomly assigned to received either 1800 mg of EPA composition (Epadel) with statin, or statin only with a 5-year follow-up. Lancet 2007; 369: 1090-98. After 5 years of treatment, subjects exhibited an increase in plasma EPA of only 70% (from baseline of 93 mg/L to 169 mg/L).

FIGS. 1 and 2 and show a comparison of the change in plasma/serum EPA levels observed with AMR101 treatment in the current study compared to those observed with different EPA compositions in the DELIS study and by Grimsgaard. As will be noted, at ˜2 g per day, AMR101 achieved much greater plasma EPA increase compared to baseline (˜4-fold) after just 6 weeks than the DELIS study observed (<2-fold) after 5 years of treatment. Moreover, at the 4 g per day dose, AMR101 treatment for 6 weeks achieved much higher (>250 μg/g) plasma EPA levels than reported by Grimsgaard after 7 weeks of treatment (87.66 μg/g serum). Overall, the 4 g per day dose of AMR101 resulted in a greater than 5-fold increase in plasma EPA over baseline while the 4 g per day dose of Grimsgaard's composition resulted in less than a 3-fold increase in serum EPA. These results were unexpected.

Example 2

A multi-center, randomized, double-blind, placebo-controlled trial was conducted in North America to determine whether 1 gram twice daily of EPA for 6 months improves motor performance in Huntington's patients. A post-hoc analysis was performed to evaluate the effect of EPA on non-fasting triacylglycerols.

Study of the effects of ethyl-EPA on the progression of Huntington Disease enrolled study participants at 41 sites in Canada and the United States. Based on the results of the earlier study, the study entry criteria were designed to enrich the participation of individuals with Huntington disease with a CAG repeat less than 45, without requiring genetic testing to reveal the length of expansions to research participants or investigators. To participate in the study, individuals had to have the clinical features of HD and either a confirmatory family history or a known CAG expansion. Eligibility criteria included a minimum age of 35, a total functional capacity of at least 7, minimal dystonia (not exceeding 2 on the UHDRS in either the trunk or extremities), minimal bradykinesia (not exceeding 2 on the UHDRS item for bradykinesia), the use of adequate birth control, the ability to take oral medications, and the willingness and ability to comply with study requirements. Individuals were not eligible to participate if, within 60 days of the baseline visit, they had used omega-3 fatty acid supplements, tetrabenazine or reserpine, high or variable doses of oral anti-psychotic medications (e.g., haloperidol), steroids other than topical preparations, high dose selenium supplements, lithium, high doses of benzodiazepines, anti-coagulation medication (e.g., coumadin), high doses (greater than 325 mg per day) of aspirin, unstable does of NMDA receptor antagonists (e.g., memantine), unstable doses of anti-epileptic medications, or if they had participated in other investigational drug studies. Additional exclusion criteria were the use of depot neuroleptics within 6 months of the baseline visit, a history of tardive dyskinesia, unstable medical or psychiatric illness, major depression (defined as a score greater than 20 on the Beck Depression Inventory II), suicidal ideation, clinically significant substance abuse within 12 months of the baseline visit, women who were pregnant or lactating, known allergy to ethyl-EPA or placebo, or previous participation in an investigational study of EPA.

This was a randomized, double-blind, placebo-controlled, parallel group study of EPA (1 gram twice/day). The institutional review board at each participating site approved the research plan and consent documents. Eligible study participants provided written consent. At the baseline visit, participants were randomized according to a block-balanced computer-generated randomization plan that was stratified by site and generated by the Biostatistics Center at the University of Rochester. Individuals were randomized in a 1:1 ratio to receive either active drug (n=158) in the form of two 500 mg capsules of AMR101 orally or placebo (n=154) in the form of two 500 mg capsules containing light paraffin oil and 0.2% dl-alpha-tocopherol twice daily orally for 6 months. After 6 months, all TREND-HD participants were treated with AMR101 for 6 months in an open-label fashion. Only data from the first 6 months were used to evaluate the effects of AMR101 on lipids.

The outcome measure of this study was the change in non-fasting triacylglycerol (TG) levels in those on AMR101 compared to those on placebo.

Safety was assessed at all study visits, including evaluation and assessment of adverse events and serious adverse events and review of clinical laboratory tests (complete blood count, serum chemistry, and urine pregnancy tests). The safety of research participants was monitored in a blinded manner by a medical monitor from both the sponsor and from the Huntington Study Group. In addition, an independent Safety Monitoring Committee that had access to treatment assignments reviewed safety data throughout the study to determine if any modifications were needed to the trial's conduct.

Changes in lipid levels were compared using an analysis of covariance (ANCOVA) with treatment group as the factor of interest, site as a stratification factor, and baseline value as a covariate. All individuals who received study medication were included in the safety analysis. For each type of adverse event, the treatment groups were compared regarding the occurrence of at least one event using Fisher's exact test. Continuous measures of safety such as laboratory test results and vital signs were analyzed using methods similar to those described above for the primary outcome variable (ANCOVA). No corrections were made for multiple comparisons in evaluating safety data.

One hundred forty-five subjects on AMR101 (92% of those assigned) and 141 of those on placebo (92% of those assigned) had red blood cell content of EPA determined at baseline and 6 months. Baseline red blood cell content of 20:5n3 (EPA) increased significantly after 6 months in those on AMR101 (from a mean of 0.52% to 3.07%) but decreased in those on placebo (from a mean of 0.61% to 0.55%); p<0.0001). After 6 months, individuals taking AMR101 had a 26 mg/dL decrease in TGs from a baseline of 171 compared to a decrease of 11 mg/dL from a baseline of 187 mg/dL in those on placebo; p=0.007. Total cholesterol was reduced significantly more in those taking AMR101 (9.5 mg/dL) from a baseline of 204 mg/dL than in those taking placebo (2.5 mg/dL) from a baseline of 208 mg/dL; p=0.009. Lipid and Motor Scoer data are shown in Tables 5 and 6, respectively.

By comparison with these data for AMR101, Grimsgaard reported a decrease (from baseline) of only 12% in serum triglycerides in the EPA group after 7 weeks of treatment. Furthermore, addition of the Epadel EPA composition to existing statin therapy in the DELIS study resulted in only a 9% reduction in triglycerides after 5 years of treatment.

Example 3

A study was performed to evaluate and compare the content of Epadel capsules with AMR101 capsules. Six capsules of each composition were selected for analysis by gas chromatography. Averages of the six capsules for each of the two compositions are shown in Table 7.

Example 4

A phase I, multiple dose pharmacokinetic study in healthy male volunteers was carried out at a single center. Twenty-four subjects were divided into two treatment groups of 12 subjects each (groups A and B). Both groups received the same total daily dose of AMR101 but the dosing regiments were different. All subjects received a single oral dose of 2 g AMR101 on Day 1. Treatment Group A received 28 continuous once daily doses of 2 g AMR101. Treatment Group B received 27 continuous twice daily doses of 1 g AMR101 and a single dose of 2 g of AMR101 on day 30.

Levels of EPA and other essential fatty acids were determined in plasma and red blood cells. Blood samples for pharmacokinetic analysis were taken at the following time points for Treatment groups A and B:

Days 1 and 30: Pre-dose, 1, 2, 3, 4, 5, 6, 8, 20, 12, 24, 36 and 48 h. post-dose;

Days 9, 16, 23: pre morning dose;

Days 37, 44, 58: post last dose.

A first Interim Report presents the following pharmacokinetic results for Treatment Group B:

Plasma—Day 1 (Pre-dose, 1, 2, 3, 4, 5, 6, 8, 20, 12, 24, 36 and 48 h post-dose);

Red cell—Day 1 (Pre-dose and 36 h), Day 30 (1 h post-dose), Day 37, Day 44, Day 58.

Using a corrected value obtained by subtracting the pre-administration concentration from the concentrations at each sampling, a single oral dose of 2 g of AMR101 resulted in a rapid rise in plasma lipid EPA. Maximum values were observed at 5 hours post-administration with EPA levels remaining above baseline at 48 hours post-administration. The half-life of removal of EPA from plasma lipids was 87±65 h (non-baseline subtracted) and 42±31 h (baseline subtracted). Summary pharmacokinetic data are shown in Table 8.

In the Per Protocol population oral administration of AMR101 resulted in RBC EPA levels increasing from a mean value of 190.4 mg/g before dosing on Day 1 to 40.3 mg/g one hour following the final dose on Day 30.

Example 5

A multi-center, placebo-controlled randomized, double-blind, 12-week study with an open-label extension was performed to evaluate the efficacy and safety of AMR101 in patients with fasting triglyceride levels≥500 mg/dL. The primary objective of the study was to determine the efficacy of AMR101 2 g daily and 4 g daily, compared to placebo, in lowering fasting TG levels in patients with fasting TG levels≥500 mg/dL and ≤1500 mg/dL (≥5.65 mmol/L and ≤16.94 mmol/L).

The secondary objectives of this study was the following:

-   1. To determine the safety and tolerability of AMR101 2 g daily and     4 g daily; -   2. To determine the effect of AMR101 on lipid and apolipoprotein     profiles; -   3. To determine the effect of AMR101 on low-density lipoprotein     (LDL) particle number and size; -   4. To determine the effect of AMR101 on oxidized LDL; -   5. To determine the effect of AMR101 on fasting plasma glucose (FPG)     and hemoglobin A_(1c) (HbA_(1c)); -   6. To determine the effect of AMR101 on insulin resistance; -   7. To determine the effect of AMR101 on high-sensitivity C-reactive     protein (hsCRP); -   8. To determine the effects of AMR101 2 g daily and 4 g daily on the     incorporation of fatty acids into red blood cell membranes and into     plasma phospholipids; -   9. To explore the relationship between baseline fasting TG levels     and the reduction in fasting TG levels; and -   10. To explore the relationship between an increase in red blood     cell membrane eicosapentaenoic acid (EPA) concentrations and the     reduction in fasting TG levels.

The population for this study is men and women (women of childbearing potential will need to be on contraception or practice abstinence)>18 years of age with a body mass index kg/m² who are not on lipid-altering therapy or are currently on lipid-altering therapy. Patients currently on statin therapy (with or without ezetimibe) were evaluated by the investigator as to whether this therapy can be safely discontinued at screening, or if it should be continued. If statin therapy (with or without ezetimibe) is to be continued, dose(s) were stable for ≥4 weeks prior to randomization. Patients taking non-statin, lipid-altering medications (niacin>200 mg/day, fibrates, fish oil, other products containing omega-3 fatty acids, or other herbal products or dietary supplements with potential lipid-altering effects), either alone or in combination with statin therapy (with or without ezetimibe), were required to safely discontinue non-statin, lipid-altering therapy at screening.

Approximately 240 patients were randomized at approximately 50 centers in North America, South America, Central America, Europe, India, and South Africa. The Phase 3, multi-center study consisted of 3 study periods: (1) A 6- to 8-week screening period that includes a diet and lifestyle stabilization and washout period and a TG qualifying period; (2) A 12-week, double-blind, randomized, placebo-controlled treatment period; and (3) A 40-week, open-label, extension period.

During the screening period and double-blind treatment period, all visits were within ±3 days of the scheduled time. During the open-label extension period, all visits were within ±7 days of the scheduled time. The screening period included a 4- or 6-week diet and lifestyle stabilization period and washout period followed by a 2-week TG qualifying period.

The screening visit (Visit 1) occurred for all patients at either 6 weeks (for patients not on lipid-altering therapy at screening or for patients who did not need to discontinue their current lipid-altering therapy) or 8 weeks (for patients who required washout of their current lipid-altering therapy at screening) before randomization, as follows:

Patients who did not require a washout: The screening visit occurred at Visit 1 (Week −6). Eligible patients entered a 4-week diet and lifestyle stabilization period. At the screening visit, all patients received counseling regarding the importance of the National Cholesterol Education Program (NCEP) Therapeutic Lifestyle Changes (TLC) diet and received instructions on how to follow this diet. Patients who required a washout: The screening visit occurred at Visit 1 (Week −8). Eligible patients began a 6-week washout period at the screening visit. Patients received counseling regarding the NCEP TLC diet and received instructions on how to follow this diet. Site personnel contacted patients who did not qualify for participation based on screening laboratory test results to instruct them to resume their prior lipid-altering medications.

At the end of the 4-week diet and lifestyle stabilization period or the 6-week diet and stabilization and washout period, eligible patients entered the 2-week TG qualifying period and had their fasting TG level measured at Visit 2 (Week −2) and Visit 3 (Week −1). Eligible patients had an average fasting TG level≥500 mg/dL and ≤1500 mg/dL (≥5.65 mmol/L and ≤16.94 mmol/L) to enter the 12-week double-blind treatment period. The TG level for qualification was based on the average (arithmetic mean) of the Visit 2 (Week −2) and Visit 3 (Week −1) values. If a patient's average TG level from Visit 2 and Visit 3 fell outside the required range for entry into the study, an additional sample for fasting TG measurement was collected 1 week later at Visit 3.1. If a third sample was collected at Visit 3.1, entry into the study was based on the average (arithmetic mean) of the values from Visit 3 and Visit 3.1.

After confirmation of qualifying fasting TG values, eligible patients entered a 12-week, randomized, double-blind treatment period. At Visit 4 (Week 0), patients were randomly assigned to 1 of the following treatment groups:

-   -   AMR101 2 g daily,     -   AMR101 4 g daily, or     -   Placebo.

During the double-blind treatment period, patients returned to the site at Visit 5 (Week 4), Visit 6 (Week 11), and Visit 7 (Week 12) for efficacy and safety evaluations.

Patients who completed the 12-week double-blind treatment period were eligible to enter a 40-week, open-label, extension period at Visit 7 (Week 12). All patients received open-label AMR101 4 g daily. From Visit 8 (Week 16) until the end of the study, changes to the lipid-altering regimen were permitted (e.g., initiating or raising the dose of statin or adding non-statin, lipid-altering medications to the regimen), as guided by standard practice and prescribing information. After Visit 8 (Week 16), patients returned to the site every 12 weeks until the last visit at Visit 11 (Week 52).

Eligible patients were randomly assigned at Visit 4 (Week 0) to receive orally AMR101 2 g daily, AMR101 4 g daily, or placebo for the 12-week double-blind treatment period. AMR101 was provided in 1 g liquid-filled, oblong, gelatin capsules. The matching placebo capsule was filled with light liquid paraffin and contained 0 g of AMR101. During the double-blind treatment period, patients took 2 capsules (AMR101 or matching placebo) in the morning and 2 in the evening for a total of 4 capsules per day. Patients in the AMR101 2 g/day treatment group received 1 AMR101 1 g capsule and 1 matching placebo capsule in the morning and in the evening. Patients in the AMR101 4 g/day treatment group received 2 AMR101 1 g capsules in the morning and evening.

Patients in the placebo group received 2 matching placebo capsules in the morning and evening. During the extension period, patients received open-label AMR101 4 g daily. Patients took 2 AMR101 1 g capsules in the morning and 2 in the evening.

The primary efficacy variable for the double-blind treatment period was percent change in TG from baseline to Week 12 endpoint. The secondary efficacy variables for the double-blind treatment period included the following:

-   -   Percent changes in total cholesterol (TC), high-density         lipoprotein cholesterol (HDL-C), calculated low-density         lipoprotein cholesterol (LDL-C), calculated non-high-density         lipoprotein cholesterol (non-HDL-C), and very low-density         lipoprotein cholesterol (VLDL-C) from baseline to Week 12         endpoint;     -   Percent change in very low-density lipoprotein TG from baseline         to Week 12;     -   Percent changes in apolipoprotein A-I (apo A-I), apolipoprotein         B (apo B), and apo A-I/apo B ratio from baseline to Week 12;     -   Percent changes in lipoprotein(a) from baseline to Week 12         (selected sites only);     -   Percent changes in LDL particle number and size, measured by         nuclear magnetic resonance, from baseline to Week 12 (selected         sites only);     -   Percent change in remnant-like particle cholesterol from         baseline to Week 12 (selected sites only);     -   Percent change in oxidized LDL from baseline to Week 12         (selected sites only);     -   Changes in FPG and HbA_(1c) from baseline to Week 12;     -   Change in insulin resistance, as assessed by the homeostasis         model index insulin resistance, from baseline to Week 12;     -   Percent change in lipoprotein associated phospholipase A2 from         baseline to Week 12 (selected sites only);     -   Change in intracellular adhesion molecule-1 from baseline to         Week 12 (selected sites only);     -   Change in interleukin-6 from baseline to Week 12 (selected sites         only);     -   Change in plasminogen activator inhibitor-1 from baseline to         Week 12 (selected sites only);     -   Change in hsCRP from baseline to Week 12 (selected sites only);     -   Change in serum phospholipid EPA content from baseline to Week         12;     -   Change in red blood cell membrane EPA content from baseline to         Week 12; and     -   Change in serum phospholipid and red blood cell membrane content         in the following fatty acids from baseline to Week 12:         docosapentaenoic acid, docosahexaenoic acid, arachidonic acid,         palmitic acid, stearic acid, and oleic acid.

The efficacy variable for the open-label extension period was percent change in fasting TG from extension baseline to end of treatment. Safety assessments included adverse events, clinical laboratory measurements (chemistry, hematology, and urinalysis), 12-lead electrocardiograms (ECGs), vital signs, and physical examinations

For TG, TC, HDL-C, calculated LDL-C, calculated non-HDL-C, and VLDL-C, baseline was defined as the average of Visit 4 (Week 0) and the preceding lipid qualifying visit (either Visit 3 [Week −1] or if it occurs, Visit 3.1) measurements. Baseline for all other efficacy parameters was the Visit 4 (Week 0) measurement.

For TC, HDL-C, calculated LDL-C, calculated non-HDL-C, and VLDL-C, Week 12 endpoint was defined as the average of Visit 6 (Week 11) and Visit 7 (Week 12) measurements. Week 12 endpoint for all other efficacy parameters was the Visit 7 (Week 12) measurement.

The primary efficacy analysis was performed using a 2-way analysis of covariance (ANCOVA) model with treatment as a factor and baseline TG value as a covariate. The least-squares mean, standard error, and 2-tailed 95% confidence interval for each treatment group and for each comparison was estimated. The same 2-way ANCOVA model will be used for the analysis of secondary efficacy variables.

The primary analysis was repeated for the per-protocol population to confirm the robustness of the results for the intent-to-treat population.

The primary efficacy variable was the percent change in fasting TG levels from baseline to Week 12. A sample size of 69 completed patients per treatment group provided 90% power to detect a difference of 30% between AMR101 and placebo in percent change from baseline in fasting TG levels, assuming a standard deviation of 45% in TG measurements and a significance level of p<0.01. To accommodate a 15% drop-out rate from randomization to completion of the double-blind treatment period, a total of 240 randomized patients was planned (80 patients per treatment group).
